BACKGROUND OF THE INVENTION

The present invention relates to a seamless 3D flat knit vamp andmanufacturing method thereof.

Woven vamp has become a new product line which has the advantages oflight, breathable and stylable, thus is welcomed by the market. However,current woven vamps are formed by firstly weaving a planar woven fabric,laying out several extended shoe-shaped vamps on the planar wovenfabric, forming jacquard or hollow patterns on corresponding parts ofthe shoe-shaped vamps, and thereafter cutting the vamps by lasermachines. However, it takes a long time for the laser machines to cutthe vamps; the costs of the machines are also high. For some vamps,after being embroidered or adhered to other fabrics, it is necessary tocarry out second cutting operation by laser machines. The manufacturingprocess is complex, and a large amount of edges, corners and remainingfabric will be wasted. Precise sewing is required for combining theplanar vamp and the sole, otherwise the size and shape of the shoe willbe affected, resulting in inconsistent shoe size and jeopardizingcomfortability and aestheticness. All the aforementioned causes highmanufacturing costs of the shoes. Besides, common woven vamps are madeof softer fabric, thus the vamps are not firm enough and easilycollapse, affecting the outer appearance of the vamps.
